A 4-pin ribbon-style jumper cable with 2.54mm (0.1") pitch connectors on both ends. A neat, reliable way to connect standard 0.1" header devices — perfboard, breadboards, breakout boards, and more — without using loose individual jumper wires.
These connectors are sometimes referred to as "Berg", "Dupont", or "Molex" style — they're a widely used generic standard. The connectors are not keyed or latched, so they can be inserted in either orientation.
Key Features
- 4-Pin Configuration – 1×4 ribbon-style cable with female headers on both ends
- 2.54mm (0.1") Pitch – Standard header spacing, compatible with most breakout boards and perfboard
- 20cm Length – Convenient length for bench work and prototyping
- Non-Keyed Connectors – Can be inserted in either direction
Ideal For
- I2C and SPI sensor connections (SDA, SCL, VCC, GND)
- Prototyping with perfboard and breadboards
- Connecting 4-pin modules and breakout boards
Package Contents
- 1× 4-pin jumper cable (20cm, female-to-female)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
